My invention relates "toa dual valve selective control handle assembly for combination faucets.

"The salientobject of my invention is thesingle handle assembly that will selectively operate two valves yby an intermediate handle shaft unit, which may `operate *eachi valve independently of the other, for a full'flow of either hot or cold liquid, 'or `operate both valves in a partialv or full open'pos'ition to mixV `both hot and cold liquid for a warm liquid, `all accomplished by valve operating vmembers Isecured on the handle 4shaft unit contacting a circular flanges section on each of the valve stem or'shaft thereof, whereby -hot and cold liquid may be obtained'in the required volume andproportion desired, and to the degree of temperature desired.

Another object ofl my invention is the valves' handle assembly constructed so that a right turn willtoperateone valve, and a'left turn will operate the other valve, Lat the same time the valve not in use will remain in 'a `closed and locked position, if both valves arerequired to operate at the same time, then, the valves locking member on the handleshaft assembly is automatically positioned 'by a turn of the handle, so that free operation f both valves are permitted at the same time, and the .volume ofV liquid .owfrom either or Vboth valves-iscontrolled to the desired degree .by meanso" one singlefhandle wheel or lever. Indicia `markings therewith may beprovided on the handle wheel or lever for the operation -required, if so desired.

AfurtherI objectof my invention is the dual valve body having two valve chambers, closely positioned` to eachother and -divided -by a Wall portion that hasa perpendicular bored hole there through in Whicha rounded handle shaft section is contained infa rotatable position.

Referring to the drawings, the numeral I designates my complete dual valve operated faucet combination and selective control handle therewith, comprising a dual valve body member 2 having two valve chambers 3 and 3a closely positioned to each other and divided by a wall portion 4 having a perpendicular bored hole 5 therethrough for a handle shaft member 6 to rotate therein. The upper end of 6a, of the handle shaft 6 is iltted into a bore 'Ia of a handle wheel 1 (or may be a lever, knob, etc.,) if so desired, which operates the shaft 6 by means of a boltscrew 8 secured in hole 9 and 9a of handle wheel 1, the bolt-screw extending through hole 9b in the upper end 6a of handle shaft. The handle wheel 'I has an upper body handle nut 6:c that is screwed into threaded portion 2t of the upper wall portion 4.

The lower rounded end I6 of handle shaft 6 is rotatably located in a bored hole I I in the lower body nut I2 having a flange portion |2a that is secured into a counterbore I2c of the lower boss portion 2a: of faucets body member 2, all of which is for the handle location and convenience thereof. A squared section I3 is immediately provided above the lower end I6 of handle shaft 6, the squared section being positioned rotatably between the washer Ia bearing against the lower portion 4a, of the faucets dividing wall section 4, and washer bearing on lower body nut I2. Holes I4 are for operating a spanner wrench to remove and secure the lower body nut I2 having threaded portion I2e that screws into a threaded portion 2r of lower boss section 2x of body member 2.

Washers I 5 and I5a are for positioning valve actuating locking and cam members 24 and 25 located and ilxed on the squared section I3 of the handle shaft 6, in which left and right valve stems I6 and I 6a are slidably inserted in each of the bores Ik of the upper valve bodys nuts |6h and within the valve chambers 3 and 3a, these valve stems having upper rounded ends I? and IIa, and lower rounded ends I8 and I8a, all slidable in bored holes I6d and I8e, respectively. The valve stems have threaded portions I9 on which the threaded holes 26s of each valve 26 and 26a are screwed down until abutting the ledges or flanges 2| and 2|a. Adjacently below and suitably spaced apart are lower circular beveled edges flanges 22 and 22a on each valve stem I6 and IEa, providing means by which the valves 26 and 26a, made of yielding and resilient material, may be operated through the selective positioning of the valve by operating members 24 and 25 secured on the squared portion I3 of shaft 6. The lower flange 22 having beveled edges b around the circumference of the flange, allows the valve operating members 24 and 25 to gradually engage the flanges 22 and 22a, which operate in a rectilinear motion either in opening or closing of the valves 26 and 26a on their respective beveled seats 26h and 26e.

The valve stem body nuts |6h has a male threaded portion |61' that screws into female threaded portions 2m and 211J in the upper central boss portion 2v of the faucets body 2, a washer I6g and a lock-nut |67- securing firmly each resilient valve on ledges 2| and 2Ia of valve stems which precisely position valve 26 and 26a onto their sats 26h and 26e, these valves having internal threaded portion 26s that screw onto threaded portion I9 of each stem I6 and I6a. Each of the valves stem body nuts I 671I have a recess portion Id to provide suitable clearance above valves lock-nuts |67'.

The two operating valve locking and cam members 24 and 25 located on squared section I3 of the shaft 6, are `positioned between the two washers I5 and |5a. The top operating member 24, which is reversible, is for closing the valves and is provided with a square hole 24a into which the squared section I3 is located, this member 24 has two extended sections 26 and 2'! extending in opposite directions from the square hole 24a of the handle shaft 6, to the working points of contact with the top of the lower flange 22 and 22a on each of the valve stem I6 and I6a. These extensions 26 and 21 are provided with beveled edge portions 29, 36, 3| and 32, that permits engagement with either of the valve flanges 22 and 22a on the valve stem I6 and I6a, for opening and closing the valves. The surfaces 26a and 27a retain firmly the valves down t0 a closed and locked position.

These valve locking arm-like extensions 26 and 21 are formed in a parallel line that is placedl olf center in a forward direction from the center of the hole in the valve closing members, this forward location of the valve closing members permit quick release of the valve opening purposes due to the very short movement required to clear the valve stem flange disks 22 and 22a, and at the same time retains the other valve ina closed position, as the short backward movement of the opposite extension portion is too short to permit release of that respective valve.

The valve opening cam member 25 is provided with a square hole 35 into which the squared section I3 of the handle shaft 6 is located, this valve lifting member 25 is provided with three extended individual fan-like segmental cam sections 36, 37 and 38, note Figures 3, 4, 5 and 6, each of these cam sections have varying plane levels, such as section 35 for right hand valve operation, has an entering or engaging beveled rise section 39 that partly opens its engaging valve 26a, it is also provided with a'higher level plane 46, which, when brought into position under the engaging stem flange disk 22a provides a full flow of cold liquid, this section 36 is also provided further with a ridge-like stop portion 4|, which controlsthe turning motion by contact with the valve stem flange 22a. Note Figure 6.

Section 3'I for the left hand valve operation, see Figure 4, has an entering or engaging beveled portion 42 that partly opens the valve 26, it is also provided with a higher level plane 43 which, when brought into position under the stem flange disc 22, provides avfull flow of hot liquid, this member 42 is also provided with a descending portion 44 terminating into a semi-lower plane or section 45, which, when in position under the left valve stem flange 22, reduces the flow of hot liquid from the valve 26, and at the same time brings into operation the extending portion .38 which is only for the right hand valve operation and has an entering or engaging lower plane section 38a which, when brought into position under the right hand valve stem flange disc 22a will raise the valve 26a to permit a desired flow of cold liquid, and at the same time permit the desired flow of hot liquid from the valve 26, this in turn positions the lower level 45 of cam section 3l under the left hand valve stem flange disc 22 and reduces the flow of hot liquid from the valve 26 to the low point for 'mildfior warmellquid'iawhich.aisilimited "by :the
